Newhouse was drafted by the Dallas Cowboys in 1972 and retired in 1983. He went to three Super Bowls and is remembered for a 29-yard touchdown pass that helped lead the Cowboys to a 1977 Super Bowl victory against Denver.

Newhouse ran for 4,784 yards during his career with the Cowboys and had two nicknames: “House” and “human bowling ball.”

He played at the University of Houston, where he broke several records and was inducted into the school’s Athletics Hall of Honor.

Former Cowboys player Drew Pearson told the Star-Telegram: "Robert Newhouse was a great teammate and friend. Loved that man. ... What's ironic is that House had a heart of gold, do anything for anyone, and it was a failing heart that finally brought the great #44 down. Sad day.”

Russell Maryland, who joined the Cowboys in 1991, told Fox 4 Dallas-Fort Worth that younger players looked up to Newhouse.

“He always gave sage advice; he wasn't too animated, but he was wise. Guys didn't always follow his advice, but he gave good advice," Maryland said.

Condolences spread on Twitter.
